MADISON, Wis. – The Wisconsin Supreme Court has vacated a contempt order that had been issued against a state commission for moving ahead with implementing key portions of Gov. Scott Walker's law effectively ending collective bargaining for most public workers.

However, the Supreme Court declined Thursday to put on hold a lower court ruling from 2012 that found the law's restrictions were unconstitutional as they applied to a Madison teachers union and a Milwaukee public workers union.

The unions claim the ruling applies to all local unions statewide, but Walker's administration says it does not.

That issue remains pending before the Supreme Court.

All the court said was that a lower court judge was wrong to find the Wisconsin Employment Relations Commission in contempt for preparing re-certification elections for hundreds of unions.
